v @Hommu 'or uncondensable vapors from within the condenser shell and todeliver 'the same into i chamber 0 The shaft S is rotated atsu'itablespeed; the steam to be condensed enters' the condenser at K and iscondensed therein and collects inthe hot well F, from which it it to theejector E in removing the air' or iin-- coudeusable vapors is diminishedand would occasion an undesired rise'in pressure within' the condensershell. This disadvantage is overcome, however, from the fact that as thecondensate diminishes, the loat e1 descends, and through the system oflinks dey scribed opens or further opens the valve t,

removed by the impeller Il, which deliversit athigher pressure, asatmospheric, into the discharge casing or volute V1, A

'The ejector E withdraws air or uncondciisable vapors from the condensershell A and delivers itthrougli the pipe j and valve m into the chamber0, and thence through the tubular projection pinto the impeller I2,which by centrifugal action further raises the 4pressure of the air oruncondensable vapors and the motive fluid from eJector E and throws itoutwardly into the con- ,densate in the spaces between the vanes ful inthe impeller Il, where the condeiisable vapors and motive Huid from theejector E are condensed by coming into contact with the condensate; andair and uncondensable vapors then move with the condensate.

through the impcller Il, which increases -their pressure, and themixture of water and air or uncondensable vapors is delivered into thedischarge casing V1 at atmosphericV pressure or higher, or .at any othersuitable 4 pressure.

only condensed steam, there is, relative to a `jet condenser of thesaine capacity, a smaller amount of water to be removed, since in a ,jetcondenser not only the condensate -but also the condensing water withwhich the condensate is mixed must 'he removed. The condensate isremoved, as described, by the inipeller I1; but in case the amount ofsteam to be'conde'nsed and entering at K be diminished, as in case; oflight load upon the engine or other device exhausting into the condenserA, the amount of condensate `might be so much diminished that the eX-tcnt of submergence of the impeller I, that is, the distance from thecondensate level b2V to the iinpeller, is so reduced that the pumpremoves a less amountl of condensate; andwith less amount of waterflowing through the'impeller I1, the assistance rendered by to allow orincrease iniiow of water from any suitable source through the pipe sin'to u the chamber 1, from'which it passes through the aforementionedpassages g1 and is delivered into the inipeller I1 into the passagesbetween its vanes ful, thus affordingadditional water supply andmaintaining the amount of water passing through the impeller I at orabove the amount necessary to produce full assistance to the ejector E.

While I have herein more particularly described a surface condenser, itwill be understood that my invention is not limited thereto, exceptwhere so expressed in the. claims,

lbut that 'my improved apparatus is applicable also to other types ofcondenser, for example, jet condensers.

It will be understood that for either or both of the ejectors E and E1may be em.- plo'yed anyl other suitable type of ejector;

lor in lieu of themv or either of them may be used 'other means forremoving gas and uncondeusable vapor from the condenser.
